IRONING-MACHINE.

To all whom it may concern:

Be it known that I, ERNEST G. MGKAY, a subject of the King of Great Britain, and a resident of Strathclair, in the Province of Manitoba, Dominion of Canada, have invented a new and Improved Ironing-Maproved means for keeping the iron hot and for rendering various parts of the machine readily accessible at all times.

My invention further contemplates means for enabling the operator to regulate the amount of pressure exerted by the iron upon the cloth or other stock operated upon thereby.

My invention also contemplates various improvements in ironing machines generally, for the purpose of increasing the efliciency thereof.

Reference is made to the accompanying drawings forming a part of this specification and in which like lettersindicate corresponding parts inall the figures.

Figure 1 is a side elevation of the machine, the movements of the iron being shown by full and dotted lines. Fig. 2 is a section on the line 22 of Fig. 1 looking in the direction of the arrow. Fig. 3 is a fragmentary plan view of the machine.

Corner posts areshown at 4-5 and at 6-7 are side rails which together with the corner posts constitute a frame. Supported by the side rails 7 is a slab 7 having generally the form of a table top. Corner plates 8-9 are provided for the purpose of strengthening the framework, which is also provided with cross bars, one appearing at 10 in Fig. 3. Secured to the framework are frame members 1112 supporting bearings 13. Engaging these bearings is a revoluble shaft 14 which carries a clutch pulley 15. A driving belt 16 engages this clutch pulley for the purpose of causing it and the shaft 14 to turn. Mounted upon the shaft 14 is a fly wheel 17 and connected with the latter is a pitman 18 which for this purpose is provided at one of its ends with a bearing 19. The pitman at its opposite end is. further provided with a bearing 20 and extending Specification of Letters Patent.

Application filed June 3, 1915. Serial No. 31,871.

through this bearing is a pin 21 carried by a slide 22. This slide is provided with a pair of bearers 23 each having in cross section the form indicated in Fig. 2 and slidably engaging the rails 24. These rails are disposed parallel with each other and are located between the rails 6.

The slide 22 is provided with a large opening 25 having generally the form of a slot, as may be understood from Figs. 1 and 2. The slide 22 is further provided with a hole 26 which merges into the slot 25. A spring 27 extends into the hole 26. The slide 22 is provided with a pair of downwardly extendlng arms 28 which are parallel with each other andconstitute boundaries for the slot 25, as may be understood from Fig. 1. Secured to these arms 28 are four guide bars 29 which are held in position by bolts 30. Slidably mounted between the arms 28 is a massive block 31 serving as a plunger, said block having considerable weight and provided centrally with a slot 32, this slot extending in a vertical plane. Below the slot 32the plunger is provided with a pair of oppositely disposed walls 33. The lower ends of the plunger 31 are beveled as indicated at 34 in Fig. 2. A bolt 35 extends through these lower ends and is used for supporting the iron which is shown at 36. For this purpose the iron is provided at its top with a bearing 37, the bolt 35 extending through this bearing. This renders the iron flexible relatively to the plunger but enables the iron to tilt or to be moved angularly to some extent, as is necessary in its movement over the goods to be operated upon. The iron 36 is provided with a compartment 38 which is closed by a door 39. By opening this door the operator can place charcoal or other heated material within the iron in order to maintain the temperature thereof. Normally the iron rests upon the slab 7 The plunger 31 is provided with a pair of slots 41 (see Fig. 2) and extending through said slots and also through the slot 32, merging into them, is a bolt 42. A hand lever 43 is journaled upon this bolt and is provided with a cam surface 44 which engages the plunger at a point coinciding with the top of the slot 32. The lever normally engages the adjacent cross bar 29 in such manner as to enable the operator, by grasping the lever and pressing down upon it, to vary the degree of pressure exerted by the iron .36. That is to say, the We ght f t plunger is normally upon the iron but the operator, by lifting the outer or free end of the lever 48, may elevate the plunger and lift the iron clear of the slab 7. On the other hand, the operator by pressing down hard upon the lever can increase the pressure of the iron upon the slab.

A 3-part clutch member is shown at 45 (see Fig. 1) and is controllable by arms 46 for the purpose of engaging and disengaging the clutch pulley 15. A hand lever 47 is pivotally mounted upon an arm 48 and by a connection 19 is in operative position relatively to the arms 46. The operator by grasping the hand lever 47 and swinging it being so manipulated as to cause the shaft 14 to rotate, the pitman 18 causes the slide 22 to reciprocate. The iron 36 is thus moved from one end of the table to the other, as indicated by full and dotted lines in Fig. 1. The operator by grasping the hand lever 13 and raising it upward causes the iron 36 to be lifted clear of the slab 7; The stock to be operated upon being rested upon the slab 7 is placed under the iron and the iron is thereupon let down upon it by aid of the lever 13, as above described. By handling the lever 47 the operatorcan cause the machine to make only a few strokes at a time, or even a single stroke or merely a portion of a stroke, as desired The compartment 38 of the iron is kept filled or partially filled with charcoal or other heating materialand the same'is replenished from time to time as required. 3

1 do not limit myself to the precise construction shown, as various changes may be made therein without departing from the spirit of the invention.

, Having thus described my invention, what I 'claim'as new and desire tosecure by Letters Patent is 1. An ironing machine, comprising a framework, a slide supported thereupon and having downwardly extending parallel arms, means for moving said slide relatively to said framework, a plunger mounted to slide freely between the arms of said slide, a

v spring carried by said slide and bearing on the plunger, means controllable at the will of the operator for moving said plunger relatively to said slide, and an iron pivotally said slide, a pair of arms carried by said slide and extending parallel with each other, a plunger located between 1 said arms and movable relatively thereto, said plunger being provided with a slot, a lever extending into'said slot and PIQVlClECl'Wlbhifl cam sur- 7 face for engaging a portion of said plunger,

' said lever being' supportedindependently of said plunger in order to be able to move said plunger relatively to said slide, and an" iron carried by said plunger.

3. An ironing machine, comprising a frame, a slide movable relatively to said frame and having downwardly extending parallel arms, a plunger mounted between the arms of said slide and movable relatively to the latter, the said plunger having a slot, a bolt extending through said slot and secured to the arms of the slide, a lever journaled upon said bolt and provided with a surface engaging said plunger in order to move said plunger relatively to said slide,.a bolt carried at the lower end of said plunger, and an iron journaled upon said bolt.

4:.- An ironing machine comprising a framework, a slide mounted to reciprocateon said framework and having depending members, means for actuating saidslide, a

plunger mounted to move. between the depending members of the slide, an iron pivotally connected with said plunger, the

the weight of said plunger. being normally upon the'iron, and a lever pivotally. connected with the slide and. engaging the plunger, the said lever, when moved in one direction increasing the pressure on the iron- Copies of this patent may be obtained for five cents each, by. addressing the Commissioner of Patents,
